    Motivation and Emotion Chapter: 8

    Instinct Approaches

    S  Motivation: Factors that direct and energize the behavior of humans and other organisms S  Includes behavioral, cognitive, and social aspects

    S  Instincts: Inborn patterns of behavior that are biologically determined rather than learned.

    S  Provides the energy that channels behavior in appropriate directions.

    Drive-Reduction Approaches

    S  Suggests that a lack of some basic biological need produces a drive to push an organism to satisfy that need S  Drive: Motivational tension, or arousal, that energizes

    behavior to fulfill a need S  Primary drives – related to biological needs of the body or of the

    species as a whole

    S  Secondary drives – related to behavior that fulfills no obvious biological need.

    Drive-Reduction Approaches

    S  Homeostasis: Body’s tendency to maintain a steady internal state S  Underlies primary drives S  Uses feedback loops S  Operates the need for food, water, stable body temperature,

    and sleep

    Arousal Approaches

    S  Belief that we try to maintain certain levels of stimulation and activity S  If stimulation and activity

    levels become too high à seek to reduce

    S  People vary in the optimal level of arousal they seek out S  Daredevil sportsmen,

    high-stakes gamblers, and criminals

    Yerkes-Dodson Curve – Optimal Arousal

    Incentive Approaches

    S  Suggest that motivation stems from the desire to attain external rewards, known as incentives

    S  External incentives “push” and “pull” behavior

    Cognitive Approaches

    S  Suggest that motivation is a result of people’s thoughts, beliefs, expectations, and goals S  Draws distinction between:

    S  Intrinsic motivation - Causes individuals to participate in an activity for their own enjoyment Extrinsic motivation - Causes individuals to do something for money, a grade, or some other actual, concrete reward

    Maslow’s Hierarchy: Ordering Motivational Needs

    S  Places motivational needs in a hierarchy

    S  Suggests that before meeting higher-order needs certain primary needs must be satisfied S  Self-actualization: State

    of self-fulfillment in which people realize their highest potential in their own way

    Other Approaches

    S  Suggested by Richard Ryan and Edward Deci (2011) S  Considered human needs in

    terms of psychological well- being

    S  Proposed self- determination theory - People have the basic needs of: S  Competence S  Autonomy S  Relatedness

    S  Changes in the chemical composition of the blood S  Glucose levels S  Insulin S  Ghrelin

    Biological Factors in Regulation of Hunger

    S  Hypothalamus S  Monitors glucose levels S  Regulates food intake S  Injury affects the weight set point

    S  Weight set point: Particular level of weight that the body strives to maintain

    S  Metabolism: Rate at which food is converted to energy and expended by the body

    Social Factors in Eating

    Societal rules

    Cultural influences

    Individual habits

    Operant conditioning

    Roots of Obesity

    S  Oversensitivity to external eating cues

    S  Insensitivity to internal hunger cues

    S  Higher weight set points

    S  Higher level of the hormone leptin

    S  Fat cells in the body S  Rate of weight gain during the first four months of life is related to

    being overweight during later childhood

    motivated primarily by a desire to avoid failure

    amount of achievement imagery in

    people’s stories

    S  Need for affiliation: Interest in establishing and maintaining relationships with other people S  Gender is a great determinant of how much time is spent

    with friends

    expressions not only reflect emotional experience but also help determine how people experience and label emotions

    Roots of Emotions

    S  The James-Lange theory S  Emotional experience is a

    reaction to bodily events occurring as a result of an external situation

    S  Drawbacks S  Visceral changes would have

    to occur relatively quickly S  Physiological arousal does

    not invariably produce emotional experience

    S  Internal organs produce a relatively limited range of sensations

    Roots of Emotion

    S  The Cannon-Bard theory S  Physiological arousal and

    emotional experience are produced simultaneously by the same nerve stimulus

    S  Rejects the view that physiological arousal alone leads to the perception of emotion
